Python在所有子目录中查找特定文件并将其复制到另一个目录/

import os
import shutil

def find_and_copy_files(source_dir, target_dir, file_extension):
    for root, dirs, files in os.walk(source_dir):
        for file in files:
            if file.endswith(file_extension):
                source_file = os.path.join(root, file)
                target_file = os.path.join(target_dir, file)
                shutil.copy2(source_file, target_file)

# 示例用法
source_directory = '/path/to/source/directory'
target_directory = '/path/to/target/directory'
file_extension = '.txt'

find_and_copy_files(source_directory, target_directory, file_extension)
